TiO2修饰Ce-MCM-41的结构表征及其光催化性能
Structure Characterization of TiO2-modified Mesoporous Ce-MCM-41 and Its Photocatalytic Performance
【摘要】 以十六烷基三甲基溴化铵为模板剂,Na2Si3O7为硅源,采用水热合成法制备了Ce-MCM-41介孔分子筛;产物经TiO2修饰,得负载型光催化剂.用XRD、FT-IR、SEM、TG-DTA等手段进行结构表征,并以罗丹明B降解为模型反应,考察Ti-Ce-MCM-41分子筛的光催化活性.
【Abstract】 The mesoporous molecular sieve Ce-MCM-41 was synthesized by hydrothermal synthesis method with cetyltrimethylammonium bromide (C16TMABr) as template and Na2Si3O7 as silica source. After it was modified by TiO2, a supported photocatalyst was prepared and characterized by XRD、FT-IR、SEM and TG-DTA. The photocatalytic performance of Ti-Ce-MCM-41 for Rhodamine B degradation was tested.
